Ii-Circuit breakers zenziwa ngokulinganisa okungafaniyo kwangoku, ukusuka kwizixhobo ezikhusela iisekethe ezisezantsi-zangoku okanye izixhobo zendlu nganye, ukuya kwi-switchgear eyenzelwe ukukhusela iisekethe eziphezulu zombane ezondla isixeko sonke.
Liperyenza i-Miniature circuit breaker (MCB) - ilinganiswe ngoku ukuya kwi-63 A, ehlala isetyenziswa kwindawo yokuhlala, yorhwebo, ukukhanya kwezoshishino.
Ii-MCBs zihlala zingatshatyalaliswa ngexesha langoku ukuze ziphinde zisebenziseke. Zikwalula kakhulu ukuzisebenzisa, zibonelela ngokulula 'kokucima/ukucima ukucinywa' ukwenzela ukwahlulwa kwesekethe kwaye njengoko umqhubi we-conductor egcinwe ngaphakathi kwebhokisi yeplastiki, akhuseleke ngakumbi ukuwasebenzisa nokusebenza.
I-MCB inakhoiimpawu ezintathu zomgaqo, i-Amperes, i-Kilo Amperes kunye ne-Tripping Curve
Umlinganiselo wangoku wokulayisha ngokugqithisileyo - iAmperes (A)
Ukulayisha ngaphezulu kwenzeka xa izixhobo zombane ezininzi zibekwe kwisekethe enye kwaye kutsalwa umsinga wombane ongaphezulu kunesekethi kunye nentambo eyilelwe ukuba ithathe. Oku kunokwenzeka ekhitshini, umzekelo xa iketile, umatshini wokuhlamba izitya, isitovu sombane, imicrowave kunye neblender zonke zisetyenziswa ngaxeshanye. I-MCB kule sekethi inqumla amandla ngaloo ndlela ikhusela ukushisa kunye nomlilo kwintambo kunye neeterminals.
Eminye imigangatho:
6 Amp- iisekethe zokukhanyisa eziqhelekileyo
10 Amp- iisekethe zokukhanyisa ezinkulu
16 Amp kunye 20 Amp- Izifudumezi zokuntywilisela kunye neebhoyila
32 Amp- Ring Final. Igama lobugcisa lesekethe yakho yamandla okanye iisokethi. Indlu enamagumbi amabini umzekelo inokuba neesekethe zamandla ezi-2 x 32A ukuze zahlule iisokethi ezikumgangatho ongasentla nasezantsi. Iindawo zokuhlala ezinkulu zinokuba naliphi na inani leesekethe ezingama-32 A.
40 Amp- Izipheki / iihobs zombane / iishawari ezincinci
50 Amp- 10kw Iishawa zombane / iibhabhu ezishushu.
63 Amp- indlu yonke
I-Liper Breakers igubungela uluhlu olusuka kwi-1A ukuya kwi-63A
Umlinganiselo weSekethe emfutshane - Kilo Amperes (kA)
ISekethe eMfutshane sisiphumo sempazamo kwindawo ethile kwisekethe yombane okanye kwisixhobo sombane kwaye inokuba yingozi kakhulu kunokulayisha ngaphezulu.
IiMCBs ezisetyenziswa kwiufakelo lwasekhayangokwesiqhelo zithelekelelwa kwi6kAokanye 6000 amps. Ubudlelwane phakathi kwamandla ombane aqhelekileyo (240V) kunye nemilinganiselo yombane yesixhobo sasekhaya esiqhelekileyo kuthetha ukuba umbane ogqithileyo obangelwa yi-short circuit akufuneki udlule kwi-6000 amps. Nangona kunjalo, kwiiimeko zorhwebo kunye nezoshishino, xa usebenzisa i-415V kunye noomatshini abakhulu, kuyimfuneko ukusebenzisa10kAii-MCBs ezilinganisiwe.
Ijika elijikajikayo
I-'Tripping Curve' ye-MCB ivumela ihlabathi lokwenyani kwaye ngamanye amaxesha iyimfuneko ngokupheleleyo, ukunyuka kwamandla. Umzekelo, iindawo zorhwebo ze-inn, oomatshini abakhulu badla ngokufuna ukunyuka kwamandla okungaphezulu kwamandla abo aqhelekileyo asebenzayo ukoyisa inertia yeenjini ezinkulu. Olu tyando lufutshane oluthatha imizuzwana nje, luvunyelwe yi-MCB njengoko ikhuselekile ngexesha elifutshane kakhulu.
Naziumgaqo ezintathu Iintlobo zeCwaveevumela iintshukumo kwiindawo ezahlukeneyo zombane:
Uhlobo lwe-B MCBszisetyenziswa kwiukhuseleko lwesekethe yasekhayaapho kukho imfuneko encinci yemvume yotyando. Nakuphi na ukunyuka okukhulu kwimekobume yekhaya kunokwenzeka ukuba kube sisiphumo sempazamo, ngoko ke ubungakanani obungaphezulu kwangoku obuvunyelweyo buncinci.
Uhlobo C MCBsiihambo phakathi kwe-5 kunye ne-10 amaxesha apheleleyo omthwalo wangoku kwaye asetyenziswa kwiiindawo zorhwebo kunye nemizi-mveliso elulaenokubonisa iisekethe zokukhanyisa ezinkulu zefluorescent, iziguquli kunye nezixhobo ze-IT ezinjengeeseva, iiPC kunye nabashicileli.
Uhlobo lwe-D MCBszisetyenziswa kwiizibonelelo zoshishino ezinzimaezifana neefektri ezisebenzisa iimotor ezinkulu ezijikajikayo, oomatshini beX-reyi okanye iicompressors.
Zontathu iindidi zee-MCBs zibonelela ngokhuseleko lokukhubeka kwisinye kwishumi lesibini. Oko kukuthi, nje ukuba i-overload kunye nexesha ligqithisiwe, i-MCB ihamba ngemizuzwana eyi-0.1.
Ke, uLiper uhlala ehlangabezana nazo zonke iimfuno zakho.
